NUMBERING APPARATUS.

SPECIFICATION forming part of l'letters Patent No. 363,975, dated May 31, 1887. Application filed April 24, 1886. Serial No. 200,050. (No model.)

To all whom it may concern.-

Beit known that I, WALTER RATHBONE BA- CON, a citizen of the United States of America,

and a resident of London, England, have invented new and useful Improvements in Consecutive-Numbering Apparatus, of which the following is a specification, reference being bad to the accompanying drawings.

of ink between them, will be prevented or avoided.

My said invention is applicable to apparatus wherein two or more sets of numerical disks or rings are mounted upon a wheel or cylinder with their axes parallel to that of the said wheel or cylinder, as described, for eX- ample,inthe specification with my application for Letters Patent, Serial No. 199,438, filed April 19, 1886.

In some apparatus of this kind as heretofore constructed the disks or'rings are placed side by side. Therefore, when ink accumulates between any two of the said disks or rings and dries or hardens it causes the said disks or rings to adhere to each other, and when one of the said disks or rings is rotated, or partially rotated, the other disk or ring will move therewith, so that the numbering will'beincorrectly effected. By my invention Ientirely obviate this defect or inconvenience, and insure correctness in the working of con secutive-nnmbering apparatus of the kind or class above referred to.

My inventionconsists in the construction and combination of devices, hereinafter described and claimed, reference be made to the accompanying drawings, in which- Figure l is a front elevation of a consecutive-numberingapparatus with my present improvements applied thereto, and comprising a wheel or cylinder carrying several sets of disks. Fig. 2 is a section of the same on the line at m, Fig. 1.

In the drawings, the letters a a indicate the numerical disks, which are fitted to rotate upon studs or shafts b, fitting one within another; and c 0 indicate the ratchet-wheels, which are fixed upon the said shafts. These ratchet-wheels are operated by pawls on the so-called deep-tooth principle. 6 e indicate the stationary plates or rings, which I arrange between the numerical disks for the purpose above specified. These plates or rings are common to all the sets of numerical disks, and are secured in any suitable manner to the'wheel or cylinder 9, for example, by means of the lugs h and screws z,- or they may be secured to some other convenient part of the apparatus, so that they will rotate therewith, but will be stationary relatively to the said disks-that is to say, they will not alter their position relatively to the said disks.

It is obvious that any ink accumulating between 'the numerical disks and the stationary plates or rings cannot cause the simultaneous rotation oftwo ofthesaid disks,nor will itet'fect the movement of either disk unless the ink should become absolutely hard, and thus prevent any movement of the disk. Therefore, while the apparatus is in working order, it must number correctly, as it is impossible for either of the said disks to carry an adjacent disk around with it.

The arrangement of ratchet-wheels 0 and parts for operating them (shown in Fig. 2) is not herein claimed, as it constitutes part of my application, Serial No. 199,438,,filed April 19, 1886.

What I claim is In a consecutive-numbering apparatus, the combination, with a wheel or cylinder g, and a series of sets of numerical disks, a, mounted on said wheel or cylinder in an annular row, of the rings 6, interposed between the disks, and each ring common to a pair ofeach set of the said annular row ofdisks, and means, sub stantially as described, for holding said rings stationary relatively to the said disks, as and for the purposes set forth.

In testimony whereofl have hereunto signed my name in the presence of two subscribing witnesses.

WALTER RATHBONE BACON.
